On rational functions without Froissart doublets
Bernhard Beckermann, George Labahn, Ana C. Matos
In this paper we consider the problem of working with rational functions in a numeric environment. A particular problem when modeling with such functions is the existence of Froiss…

Algebraic properties of robust Padé approximants
Bernhard Beckermann, Ana Matos
For a recent new numerical method for computing so-called robust Padé approximants through SVD techniques, the authors gave numerical evidence that such approximants are insensitiv…

Equilibrium problems for vector potentials with semidefinite interaction matrices and constrained masses
Bernhard Beckermann, Valery Kalyagin, Ana C. Matos +1
We prove existence and uniqueness of a solution to the problem of minimizing the logarithmic energy of vector potentials associated to a -tuple of positive measures supported on…
